[Rd] would like to configure help.start() point to a http:// style url rather than ~/.R/doc etc (fwd)

Eh? help.start.R is written in R... However, since it's mostly
paste()ing together shell commands it may come across as something
from another language.

There's a remote= argument that you can pass to help.start [try
help.start(remote="http://stat.ethz.ch/R-alpha/")] , but it
doesn't solve the whole issue, e.g. a subsequent help(help) command
will cause a warning:

Using non-linked HTML file: style sheet and hyperlinks may be incorrect in: help(help) 

and proceed to try and get


rather than something relative to the remote tree. 

I would seem that some of this stuff could do with a little redesign,
so suggestions are welcome. (The idea of having ~/.R is also
problematic if two R sessions for the same user both want to do

Notice that using a remote documentation tree is going to lose you
some of the functionality that is normally present in the system: The
set of libraries available to a user may partly sit in his or her home
directory and the .lib.loc vector specifies which locations to search
for libraries. So it's not just a matter of specifying a document
